Neil Patrick Harris had a pair of underwear sewn into his pants to conceal his private parts during the Academy Awards on Sunday (22.02.15).

The 41-year-old host appeared on stage in just a pair of tight white Y-fronts during the ceremony as a joke mocking the Best Picture winner, 'Birdman', and required extra thickness to his underwear because his member was visible under the stage's strong lights during rehearsals.

Speaking on 'Live! With Kelly and Michael', wrote: "With the lights, they see through things [in rehearsals]. We had to do something so you couldn't tell my religion.

"They had to take a second pair of underwear and sew it to the first so you couldn't see through it."

While the comedian admitted to having double-layered pants, he insisted what viewers saw was entirely his own manhood and he used "no sock" or any other padding to enhance his bulge.

The 'How I Met Your Mother' star - who is married to actor and chef David Burtka - added he had no qualms about stripping off for the segment of the show because he previously appeared on stage in tight leather hot pants as a transgender singer in Broadway show 'Hedwig and the Angry Inch'.

He told E! News: "I did 'Hedwig', so I'm used to being on stage without much on."
